Simpluna is an app for recording and predicting menstrual days. Launch the app to display a calendar where you can check your next predicted menstrual period and past menstrual days at a glance. Simpluna has an extremely simplified design, eliminating all unnecessary features to ensure it does not interfere with your daily life.

We provide Simpluna to be a tool that users can easily use daily. Therefore, we have determined that subscriptions for paid features would not be desirable and only charge customers once.

You might want to use some more features for free, such as ovulation day management, color themes, etc. The minimal number of free features is because we do not display any ads to improve the user experience. We believe that it is more important to be able to use an app without ads and stress than to have ads constantly displayed and many functions for free.\n\nWe have kept the cost of the app to the bare minimum; however, don't hesitate to reach out should you have any concerns. We would love to hear your opinion.
